Description

梨浓汁清汁的制备方法
技术领域
本发明涉及果汁，具体是一种梨浓汁清汁的制备方法。
背景技术
随着人们生活水平的提高，对天然、安全、营养的饮料的需求量越来越大，要求也越来越高。于是各种水果清汁饮料应运而生。但传统的方法制备的清汁饮料，有的是有沉淀、不清澈，有的是工序太繁琐。
梨果鲜美、肉脆多汁、酸甜可口，风味芳香优美，具清肺养肺的作用。科学家称梨是“全方位的健康水果”。但梨果采收集中，不能周年供应，加工成浓汁清汁是一条很好的途径。
发明内容
本发明的目的是为克服现有技术的不足，而提供一种梨浓汁清汁的制备方法。
实现本发明目的的技术方案是：
一种梨浓汁清汁的制备方法，包括如下步骤：
1、选择成熟新鲜的梨去皮去核，切成碎块；
2、加入纯净水打成浆；
3、用60-100目袋式过滤器过滤除渣，得粗滤液；
4、在粗滤液中加入果胶酶，酶解50-60分钟；
5、将酶解液用板框压滤机微滤，得到梨的浓汁清汁；
6、将步骤5得到的梨浓汁清汁，经杀菌灌装。
步骤2所述的加水量为果重的1-2倍；
步骤4所述的果胶酶的加入量为粗滤液重0.6-0.8‰；
步骤5所述的微滤膜，膜孔径0.5-0.8μm，进口工作压力为
1.5-2MPa；
步骤6所述的超高静压处理，压力100-500MPa，时间30-60分钟。
本发明的优点是：
1、果汁经过粗滤和微滤，除去了微粒、悬浮物、杂菌、胶体等，果汁清澈透明；
2、采用超高静压处理杀菌，果汁营养成分无损失、风味不改变。
具体实施方式:
一种梨浓汁清汁的制备方法，具体步骤是：
1、选择成熟新鲜的梨削皮去核，并切成碎块；
2、加入果重1.5倍的纯净水后打浆；
3、用80目袋式过滤器过滤除渣，得粗滤液；
4、在粗滤液中加入滤液重0.7‰的果胶酶，酶解50分钟；
5、将酶解液用孔径0.5μm的板框压滤机微滤膜（MF）微滤，工作压力1.5MPa，除去微粒、悬浮物、杂菌胶体等，得到浓汁清汁；
将梨浓汁清汁用压力300MPa的超高静压处理30分钟，灌装即成。
